A switch includes: an actuator; a conductor having a length extending between two ends and a width extending between two sides, the conductor having a connection contact at either end and at least one switching region disposed between the connection contacts, each switching region extending between two sides of the conductor and including: a hole through the conductor, at least one shearable portion bounded by the hole and a nearest of the two sides of the conductor, and an insert conductor inserted into the hole and in electrical contact with the conductor, via the hole, such that a current conduction path is defined along the length of the conductor via the insert conductor and the at least one shearable portion of each switching region; and a moveable member aligned with the at least one switching region and arranged to move in a first direction.

Switch with actuator

A switch includes: an ignition chamber; a pyrotechnic actuator for releasing gas into the ignition chamber upon ignition; a first conductor and a second conductor, the first and second conductors including connection contacts; a third conductor moveable in a direction from a first position towards a second position upon actuation by the pyrotechnic actuator; and a breakable retaining member for retaining the third conductor in the first position prior to actuation by the pyrotechnic actuator, the retaining member breaking upon actuation of the pyrotechnic actuator to allow movement of the third conductor. In the first position, the third conductor is arranged between, and in electrical and physical contact with, the first and second conductors to define a current conduction path. In the second position, the third conductor is electrically and physically separate from the first and second conductors.

Switch with pyrotechnic actuator

An electrical switchgear includes: a housing; at least one first contact mounted in the housing; at least one second contact translationally movable within the housing in a translational movement direction; a switchgear control mechanism having a first rotary element having a first rotation axis and a second rotary element having a second rotation axis; and a link element pivoted on one end thereof to the first rotary element and on an other end thereof to the at least one second contact. The first and the second rotation axes are arranged substantially perpendicular to each other. The second rotation axis is arranged essentially in parallel to the translational movement direction of the at least one second contact. The first and the second rotary elements engage such that a rotation of the second rotary element is transmitted to the first rotary element.
